I want to loop through a portion of an Array in Swift, not the entire array based on the index. The array is coming from an API so I don’t know the number of elements in advance.
For example for the array ["Joe's pizza","Sal's Pizza","Pizza Hut"]
, I would only like to loop through up to the first three (if there three) and then stop. In some cases, the starting array will have less than 3 elements and in other cases more then 3 depending on what the API returns.
My code as follows does not work.
let myArray = ["Joe's","Sal's","Pizza Hut","Domino's","John's","Pizza King"]
let numElements = myArray.count
if numElements = 0 {
print("none found")
return
}
var i = 0
var str = ""
while i <= 2 {
for i in 1...numElements-1 {
print(i)
str = myArray[i]
print(str)
}//end for loop
i+=1
}//end while loop
The code will print the full 6 and not respect the while condition. If I put the while inside the for loop, it will needlessly go through the whole Array which could be quite long even though I only want up to the first 3
How can I limit the range used in the index (when I don’t know if the actual array count is less than or greater than the number I’m seeking.
Thanks for any suggestions.
